\. HOT-WATER BOILER.

SPECIFICATION forming part of Letters Patent No. 523,860, dated July 31, 1894.

i Application filed March 12, 1894. Serial N0. 503,221. (No mode1.)-

To all whom it may concern:

Be it known that'l, DANrEL MUNsoN, of Syracuse, in the county of Onondaga, in theState of New York, have invented new and useful Improvements in Hot-Water Boilers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention is designed chieliy for heating water to be circulated through radiators located in the apartments of a building to be heated. l l The invention consists first in an improved organization of the species of boilers which have a series of water-heating pipes which extend horizontally from a header at the front of the combustion chamber toward the rear, and thence downward to another header in the rear lower part of the combustion chamber.

My said improvements embodying a novel construction of the headers of the boiler and disposition of said headers in relation to the lire-box and smoke-exit-pipe, whereby a hot water receivingr and mixing chamberl is ex` posed directly to the products of combustion over the fire-box and presents a broad straight continuons wall across the front of the com-Y bustion chamber, said header is thus edectually impinged by the fire and protects the front wall proper of the combustion chamber from the heat. VThe hot water-distributing pipe or pipes are attached directly to said header and thus promotes the :circulation of the water through the boiler by the rapid expansion of the water in said header and free escape of the heated and expanded water from the same, while the header at the opposite end of the boiler consists of a chamber forming a solid partition horizontally across the rear end of the combustion chamber beneath the smoke-exit located in the rear Wall of the combustion chamber. The bottom of this latter header isv thus isolated from the products of combustion and therefore maindiators located in the apartments of the buildingl to 'be heated, all as hereinafter more fully described and specifically set forth in the claims. y

In the annexed drawings, Figure lis a vering my invention. Fig. 2 is a vertical transverse section online-X-X-in Fig. l. Fig. 3 is a horizontal transverse section on line fY-Y- in Fig. 1. Figa is a detached face View of one of the heads of the boiler, a portion of one of its broad sides being broken away to show the internal construction of said head and Fig. 5 is a transverse section on line -Z-Z- in Fig. 4.

spending parts.

-O- represents the combustion chamber which incloses the boiler, -B- denotes the fire-box which is separated from the rear portion of the combustion chamber by the bridgewall -D- and -c-orepresents the series of water-heating pipes which extend horizontally from the upper part of the combustion chamber -C-` rearward and thence downward to the lower rear portion of the same and are connected at opposite ends to the headers'-A-A.

In order to more elfectually promote the circulation of the water through the boiler and increase the efficiency of the boiler, I form each of said headers of a row of tubes ttunited by solid continuous walls and with ports 4t/ 155e in their adjacent sides to permit re communication between said tubes and free circulation of the water throughout the header. Said headers are thus made to constitute perfect partitions across the interior of the combustion chamber. The walls of the headers are corrugated to conform to the contour of the interior of the joined tubes -tt and thus increase the heating surface of the headers.

The header AV I place directly over the cause said header to be impinged by the iire and thus effectually heat the water contained in the header. The pipes a1h which conzontally across the lower portion of the comtical longitudinalsection of a boiler embody-y Similar letters of reference indicate corref IOC bustion chamber and the smoke-exit pipe -P--is connected to the rear wall of the combustion chamber immediately above the said header and thus isolates the bottom of header from the products of combustion and maintains said header comparatively cool.

The water return pipe or pipes c1/ are connected to the header -A- and by keeping the latter much cooler than the main portion of the boiler, the iniiuX of the return Water to said header is facilitated.

In the operation of the boiler, the return Water becomes thoroughly distributed throughout the header -A so that all the pipes -c-care equally charged with the Water which by the rapid expansion of the Waterin the front header -A-, is caused to rapidly pass from the cooler rear head A through the pipes cc to the header A in which the water becomes thoroughly mixed while furtherheated and is thence distributed to the radiators by the pipe or pipes .a-,

In order to permit the boiler to be adjusted for supplying an increased number of radiators when desired, I form each of the tubes -t-t of the headers with a screw-threaded orifice u for the attachment of either a screw-threaded plug -U- or a pipe ct-f.

What I claim as my invention is- 1. In combination with theA combustion chamber C, lire-box -B- and pipes -c -carranged as shown, the hot water receiving and mixing header -A- and return Water receiving header -A consisting of hollow partitions formed with continuous solid walls and disposed respectively vertically directly over the tire-box to be exposed to the tire and extending across the combustion chamber and horizontally across the lower portion of the rear of the tire-box, and the exit-pipe -P- extending from the rear Wall of the combustion chamber immediately above the rear header and isolating the bottom of said header from the products of combustion each of said headers being provided with a plurality of orifices for attaching thereto more or less removable plugs and hot Water distributing pipes and cold Water return pipes and thus permit the said boiler to be adapted for heating directly more or less radiators as set forth.

2. In combination with the combustion chamber C and pipes -c-c, the headers -A-A each'cast in one piece and consisting of a row of tubes -t-tunited by solid continuous walls and provided with communicating ports -iY-tin their adjacent sides and with screw-threaded orices u-u in theends of the tubes for the attachment of either plugs or pipes substantially as described and shown.

In testimony whereof I have hereunto signed my name this 7th day of March, 1894.
